BoulderBadgeDad 13dca2dea6 Cover Art Filler: write cover.jpg to the RESOLVED folder, not the raw DB path (Sokhi — the actual bug)
THE bug behind "embeds art but never writes cover.jpgs": _fix_missing_cover_art
passed `details['album_folder']` (= dirname of the raw DB path, e.g. Jellyfin's
/data/music/...) as the target folder. That path doesn't exist inside the
SoulSync container — only the resolved /app/... path does. So apply_art_to_album_
files' `os.path.isdir(target_dir)` was False and the ENTIRE cover.jpg block was
silently skipped: embedding still worked (it uses the resolved paths) and the DB
thumb updated, but the sidecar was never written. Exactly Sokhi's symptom + the
"Cover art already present — database thumbnail updated" toast (cover_written
stayed False).

Fix:
- _fix_missing_cover_art: derive the folder from the RESOLVED file
  (os.path.dirname(resolved[0])), never the raw album_folder.
- apply_art_to_album_files: bulletproof it — if the passed folder doesn't exist,
  fall back to the real directory of the files instead of silently skipping.

Tests: a non-existent folder still writes cover.jpg to the real file dir. 1348
cover/art/repair tests pass.
